Abstract
As to a telecine video signal (Sv), in a telecine video signal detector (Dtp) for detecting a scene-change part (SC) and deciding whether successive telecine conversion has been carried out, a motion detector ( ) detects a motion between video signals (Sv) one field apart from each other; a first statistical processing unit ( ) accumulates detection results (Sm) for one field; a first telecine decision unit ( ) decides whether the field represents telecine-converted video; the second statistical processing unit ( ) detects statistical information (Ss ) of the input signal (Sv); a scene-change detector ( ) detects a scene-change in the output (Ss ) from the second statistical processing unit ( ); a second telecine decision unit ( ) decides field continuity from a detection result (Ssc) of the scene-change detector ( ) and a result (St ) of the first decision unit ( ); and then an AND circuit ( ) carries out an AND operation on outputs (St , St ) from the first and second decision units ( ).
